Tetrahydrofuran, an important organic chemical material and a fine chemical raw material, is widely used in resin solvents (tape coating, PVC surface coating, reactor cleaning, glass paper coating, plastic printing ink, thermoplastic polyurethane coating), reaction solvents (Grignard reagent, alkali alkyl metal compound and alkali aryl metal compound, aluminum hydride, boron hydride and organic high polymer), chemical intermediates (polytetramethylene ether, generated from tetrahydrofuran and 1,4-butylene glycol through polycondensation is called PTMG for short and polytetramethylene through further polycondensation is called PIG for short, tetrahydrofuran polyether through ring opening polymerization can be used as raw materials for producing spandex as well as natural gas odorant), chromatographic solvent (Gel permeation chromatography).
